How to add 2D symmetry line for magnetic fields when it is not radially symmetric

Please login with a confirmed email address before reporting spam

Hello,

I have a 2D simulation of AC-DC system which has perfect symmetry in the center (along the x=0 line), but the system is not axi-symmetric. Current travels through copper wires which are surrounded by magnetic material, and the system can then be extended in the z-direction to infinity (as seen in fullModel.JPG). In my actual system, this 2D model is extended in the Z-direction for 5 mm, and therefore there is no radial symmetry.

I would like to speed up my simulations by adding a symmetry boundary to the center of the model shown in fullModel.JPG, but I cannot figure out how to do so. The geometry would look like that shown in symmetryModel.JPG. I am using the magnetic fields physics package.

Does anyone know how to do this?

Thank you very much in advance.
